Embodiment Construction

[0034] The present invention will be further described below in combination with specific embodiments.

[0035] For example, exploit the vulnerabilities of the ModbusTCP protocol in the industrial control system.

[0036] 1) Grab the data packets in the network through the protocol analysis module, store and analyze the valid data, and then send the obtained protocol format and other information to the data construction module. By capturing and analyzing the data packets, the ModbusTCP data frame format can be known, including the MBPA message header and the PDU data unit. Among them: the MBAP message header includes 4 parts of the transmission flag, protocol identifier, length and unit flag, a total of 7 bytes; the PDU data unit is in the same format as the Modbus protocol, including two parts, the function code and the data field. At the same time, the population size of this test is set to 100 according to the characteristics of the industrial control system.

Abstract

The invention discloses an industrial control protocol vulnerability mining system based on a fuzzy test. The system comprises a protocol analyzing module, a data construction module, a genetic variation module, a session management module, an agent module, a drive module and an auxiliary tool module; the genetic variation module, the session management module and the agent module are connected with the drive module; the protocol analyzing module is connected with the data construction module and then is connected with the genetic variation module; and the drive module is used for connecting a test target. According to the system, the conditions of the tested target can be learned and analyzed; related data such as test scripts and a test case are specifically constructed according to the analyzed information; the hit rate of the test case is increased through analyzing the tested target; in a test process, the generation method or variation direction of the test case is adjusted specifically according to the information such as the current state of the tested target and the feedback of the test case; the vulnerability mining efficiency is improved through an efficient adjusting algorithm; and moreover, the system adaptation is increased.

Description

technical field [0001] The invention relates to a loophole mining method in an industrial control system, in particular to a communication protocol loophole mining method in the industrial control system. Background technique [0002] The industrial control system is an important part of the country's key infrastructure. It is widely used in the fields of petroleum and petrochemical, water conservancy and electric power, food processing and sewage treatment, mainly for data acquisition and production control. With the continuous deepening of the integration of informatization and industrialization, industrial control systems are gradually changing from traditional closed environments and single systems to open environments and complex multi-systems. The development brought about by deepening integration has also brought many problems that were not faced before, the most serious of which is the problem of security. [0003] With the addition of emerging Internet technologies...
